I wish to solve the following set of ODE. $ $ i\frac{d}{dt}B_{n}\left(t\right) =f\sqrt{\left(P-n\right)\left(n+1\right)}B_{n+1}\left(t\right)+f\sqrt{n\left(P-n+1\right)}B_{n-1}\left(t\right) + Y\left[\left(P-n\right)\left(P-n-1\right)+n\left(n-1\right)\right]B_{n}\left(t\right)$ $ The question is similar to the Solving n simultaneous differential equation.It’s working perfectly for N=2 case. But the method is not giving any results for larger N with larger time say t=0 to 3000, and varying constants. Values ofRead more
